Features 1、Cooperate with the travel switch to realize the CW and CCW of the motor, so that the travel is within a fixed range. 2、The weak current signal expands to control the strong current equipment, with the strong control the weak, safe and stable. 3、Combining the "power button" with the vibration sensor can trigger an alarm and effectively prevent accidents. 4、High-level trigger input mode, that is, above 1.0V is considered to be on, and the switching signal output voltage range is between 1.0V-30V. 5、Small size, easy to carry and store, convenient to use and with good performance. Specification Item Type: Relay Module Working Voltage: 12V DC Quiescent Current: 2mA (with power indicator light, 0.5mA without indicator light) Working Current: 45mA Anti-Jamming: The anti-jamming time of the input switch is 20 milliseconds, that is, when the switch is less than 20 milliseconds, it is considered as an interference signal and will be ignored. Output Mode: Relay contact, uncharged (commonly known as dry contact) COM: Common NO: Normally open, that is, the module is disconnected from COM when it is not connected to power (or closed). NC: Normally closed terminal, that is, the module is connected to COM when it is not connected to power (or closed). Output Capacity: Maximum 10A250V AC, or 10A30VDC (DC) Module Size: Approx. 58 x 32mm / 2.3 x 1.3in Height: Approx. 18mm / 0.7in Mounting Holes: Approx. 54 x 28mm / 2.1 x 1.1in Hole Diameter: Approx. 2.6mm / 0.1in Terminal Description: V+COM: The positive input of the module power supply, which is also the common line of the two switches. V-: The negative input of the module power supply. ON: Turn on the button, press the relay to immediately pull in, and keep pulling in (until the OFF button is pressed). OFF: Shut down button, press the relay to disconnect immediately. Package List 1 x Relay Module
